b) If the pressure exerted on a sample is 0,75 atm and the temperature is – 114°C, in what phase does the substance exist? c) If you measure the vapour pressure of a liquid sample and find it to be 380 mm Hg, what is the temperature of the liquid phase? d) What is the vapour pressure of the solid at - 122°C? e) Which is the denser phase – solid or liquid? Explain briefly.
